Statistics Study Lite
-- v3.19.3 January 28, 2021
(30 Statistics Functions / 42 Statistics Study Notes)
Statistics Lite provides basic descriptive statistics such as sum, sum of square, mean, sum of squared deviation, variance, standard deviation, median, mode, momentum, skewness, kurtosis, box-and-whisker plot, and frequency table,
It also provides various statistical tables such as z-table, t-table, Chi-square table and F-table.
Using this app you can find various critical values from z-distribution, t-distribution, Chi-square distribution and F-distribution. You can also compute probability from binomial distribution and Poisson distribution.
The following is the list this app provides:
Line Plot, Stem-and-Leaf Plot, Frequency Table, and Histogram
Finding Probability with Normal Distribution
Finding t Critical Values
Finding Chi-Square Critical Values
Finding Binomial Distribution and Probability
Finding Poisson Distribution and Probability
Finding Geometric Distribution and Probability
Confidence interval for the mean.
Test for a population mean
Test for two population means
Test for the difference of paired sample (paired t-test)
Person Correlation Test
Regression Analysis (Linear, Exponential)
Chi-Square Goodness-of-Fit Test
Chi-Square Independence Test
One Proportion Test
Randomness Test for the Sequence (with Monte Carlo Simulation)
Find Inverse Matrix
Solving Linear System of Equations
The following work can be done also:
1. Switch rows and columns
2. Random number generator with size, minimum and maximum
3. Random number generator from a normal distribution with size, mean, and standard deviation
